Research progress on tissue prolapse in coronary stents
Optical coherence tomography(OCT)can provide in vivo coronary artery imaging with close to histological resolu-tion.In the practice of OCT examination,researchers found that tissue prolapse(TP)after stent implantation is a very common phenom-enon.Factors such as plaque characteristics,stent design,plaque load,necrotic core,and inflammatory status may be closely related to this phenomenon.At present,the treatment strategies for TP have not been standardized,and measures based on comprehensive analy-sis of risk stratification and risk factors have their own limitations.Measures based on comprehensive analysis of risk stratification and risk factors have their own limitations.This article mainly reviews the risk stratification,predictive factors,and intervention strategies of in-stent tissue prolapse.
